• FIGS 1 — 6 show a first embodiment of the present invention illustrating a portable electronic device 10, such as a mobile telephone, mobile computing device or PDA (Personal Digital Assistant), comprising a base 12, a keypad 14 and a display unit 16.
• the keypad 14 and the display unit 16 are moveably connected to the base 12 such that the keypad 14 is configured to slide relative to the base 12, and the display unit 16 is configured to both slide relative to the base 12 and also pivot relative to the base 12 so as to be inclined at an angle relative to the base 12.
• the base 12 has a front edge 12a and a rear edge 12b, and includes a keypad recess 18 open at the front edge 12a to accommodate the keypad 14 and to define its range of sliding motion between a retracted storage position (see Figures 1 and 5) in which the keypad 14 is fully received within the keypad recess 18 in the base 12, and an extended operative position (see Figures 2 — 4 and 6) in which the keypad 14 extends from the base 12 out of the keypad recess 18.
• the base unit 12 includes a biasing member (not shown) which biases the keypad 14 into the extended operative position.
• the display unit 16 is mounted to the base 12 so that it is moveable from a retracted storage position (see Figures 1 and 5) in which it lies flat against the base 12, to an extended operative position (see Figures 2 - 4 and 6) in which it is slid backwards relative to the base 12 and also inclined at an angle relative to the base 12.
• the display unit 16 is connected to the base 12 by an arm 20 located proximate the rear edge 12b of the base 12.
• a first end of the arm 20 is rotatably located in a pivot recess 22 in the base 12, and the opposite end of the arm 20 is pivotally connected to a lower face 16a of the display unit 16 by connecting rod 24 which extends through a connecting bore 26 in the display unit and through an aperture in said opposite end of the arm 20.
• the display unit 16 is also connected to the base 12 proximate a front edge 16b of the display unit by sliding mechanism (not shown) which allows the front edge 16b of the display unit 16 to slide relative to the base 12, and also allows the display unit 16 to pivot relative to the base 12 about the sliding mechanism.
• the keypad 14 and the display unit 16 are connected by a mechanism 30 which links movement of the display unit 16 with movement of the keypad 14.
• the mechanism 30 comprises a pair of belts 32 formed in a substantially 'S'-shaped configuration within the base 12. One end of each belt 32a is secured to the base 12 proximate its teat edge 12b. Each belt then extends forwardly to and over a keypad roller 34 which extends though the key pad 14 at its rear edge 14a. Each belt 32 then passes back on itself and over a base roller 36 formed proximate to and disposed above where each belt is secured to the base 12. Each belt then extends forwardly again and its opposite end 32b is secured to a part of the display unit 16 proximate the front edge 16b thereof. Each belt is therefore held under tension by the biasing member (not shown) urging the keypad 14, and thereby the keypad roller 34, forwardly into the extended operative position.
• the connecting mechanism 30 and the arm 20 described above provide the keypad 14 and the display unit 16 of the first embodiment of the invention 10 with cooperative movement as described hereafter.
• each belt 32 is in the position shown in Figure 5, in which the keypad roller 34 is disposed proximate the base roller 36 and a large proportion of each belt 32 is disposed between the front edge 16b of the display unit 16 and the base roller 36.
• the user moves the display unit 16 by sliding it rearwards relative to the base 12 in the direction of arrow 'A' in Figure 1.
• This movement feeds each belt 32 rearwards allowing each one to pass over the base roller 36 and since the first end 32a of each belt is fixed to the base 12, each belt 32 is pulled over the keypad roller 34, as the keypad 14 is allowed to move forwards under the force of the biasing member (not shown) to the extended operative position.
• the keypad 14 continues to slide out of the base 12 under the force of the biasing member.
• the lower face 16a of the display 16 is also connected to the base 12 by the pivotable arm 20 as well as by the sliding mechanism (not shown), the movement of the display 16 is guided so that as the front edge 16b of the display unit 16 is drawn rearwards, the arm 20 elevates away from the base 12 and the display unit 16 tilts upwards to be inclined at an angle to the base 12, as shown in Figures 2 - 4 and 6.
• the above configuration of the portable electronic device provides the user with the ergonomic benefit of having a screen of the display unit 16 inclined with respect to the keypad 14, thereby making the device 10 much easier to use when, for example, placed on a work surface or held in the hands. Furthermore, the coupled movement of the keypad 14 and the display unit 16 make the opening of the device from the storage position to the operative position simpler, quicker and easier to achieve.
• each belt may be or may incorporate connections and/or wires linking the keypad 14 to the display unit 16. This would mean that the belts would have the dual purpose of operating the coordinated opening and closing of the portable electronic device 10, as well as providing the electrical connection between the two components, thereby saving space in the device.
• the connecting rod 24 in the display unit 16 may be located in a connecting slot rather than a connecting bore 26 (see reference 26a in dashed lines in Figures 1 and 2). The would allow the motion of the display unit 16 to initially slide rearwards flush with the base 12 when the device 10 is moved to the operative position, before it then tilts relative to the base 12, as the connecting rod 24 slides within the connecting slot 26a, until the connecting rod 24 reaches the end of the connecting bore and the arm 20 is then forced to tilt upwards away from the base 12, thereby causing the display unit 16 to tilt upwards.

• the portable electronic devices may be provided with a locking mechanism (not shown) such as a latch, which is operable to secure the device in the operative and/or storage position.
• a locking mechanism such as a latch, which is operable to secure the device in the operative and/or storage position.
• guide pins 118 and guide slots 116 may be reversed within the scope of the invention - such that the guide pins 118 may be provided on the display part 106 and the guide slots 116 may be provided on the base 102.
• Figure 15 shows a method of reconfiguring an apparatus of the invention.
• Sl involves moving one of a first or second part relative to the base.
• said first part is a display unit and said second part is a keypad.
• S2 shows the other of the first and second parts being caused to move relative to the base by the mechanism which couples the first and second parts, as the one of the first and second parts is moved.
• S3 shows one of the first and second parts tilting relative to the base.
• the display unit tilts relative to the base.
• the display unit may be manipulated between a retracted position and an extended position which causes the mechanism coupling the display unit to the keypad to move the key pad respectively between a retracted position and an extended position.
• the keypad may be manipulated by a user to move between a retracted position and an extended position, which then causes the mechanism coupling the display unit to the keypad to move the display unit respectively between a retracted position and an extended position.
• the keypad may include some feature to facilitate movement of the keypad from the retracted position to the extended position, such as, for example, a finger slot or cavity to enable a user to withdraw the keypad.
